i'm aspiring to be a new limewire user, but i'm having an issue downloading the software...

from the limewire website, after clicking "Mac OS X" (i run Tiger), a window opens saying "You have chosen to open LimeWireOSX.dmg" so i say yes, save it. all i get is an .exe file on my desktop and no viable program that i can run. i've tried this probably a dozen times from different places, but all i get are blank files called Slaap9qt.exe or 2i8s76b6.exe...

hope someone can help me. :/
